The page cited '/reborn HEAD 9a0ca0d' and that address no longer resolves, for two reasons it now records: * the repositories were merged into one monorepo (65cefa7), so HANDOFF.md is docs/port/HANDOFF.md **here** and its provenance is a sha in this history -- a sha from the old repo cannot be looked up at all; * /reborn is still mounted but is now an EMPTY DIRECTORY, so a test for the mount passes and every read under it fails with ENOENT. Staleness is now checkable in one command instead of by trusting a date: `git log -1 --format=%h -- docs/port/HANDOFF.md`. Three rows were listed as blocking that HANDOFF has since answered: * Q4 -- and the old row was WRONG, not merely stale. It said A on NEW GAME 'hangs the emulator'. Q4 now reads measured for all five buttons, NEW GAME -> DIFFICULTY -> SELECT DATA, 'not a hang'. This is what unblocks P5. * Q9 -- one A skips a movie, measured. P4 had already taken it; the row survived only because nobody deleted it. * Q6 -- answered as a negative with a stated reach (the driver is code, not data, four search spaces closed), which is not the same as unsettled. The five asks are recorded with what came back: four answered at9ca1eb5, and only ask 4 (rotation) still open -- with the human, not the RE agent. Adds one question the port raised and did not guess: whether the focus ring spins while focused. Its group ends 0 -> 360 deg on the untimed keyframe, and 'groups hold' cannot decide it, because 0 and 360 are the same pose.

Sylpheed
A clean-room reverse engineering and port project for Project Sylpheed: Arc of Deception (Xbox 360, 2007).
Three things live here, in one repository so that a change spanning them lands as one commit:
| The decoders | crates/sylpheed-formats — the disc's formats, read and verified disc-wide |
| The port | port/ — a Godot 4 project, plus crates/sylpheed-export which converts a disc into the open asset tree it reads |
| The corpus | docs/re/ — what has been reverse engineered, with its evidence, its retractions and its dead ends |
You need your own copy of the game. No game content is in this repository and none ever will be. The exporter reads the disc you supply.
The oracle is the real game
sylpheed-cliand the Explorer are tools for verifying our decoding. They are hypotheses under test and they have been wrong. When something must be checked against the truth, the truth is the game running in Xenia Canary, captured — not any renderer of ours.
This is stated first because getting it backwards is the most expensive mistake this project has made.
Layout
crates/
sylpheed-formats/ the decoders. Disc-wide verified; the corpus is its spec
sylpheed-cli/ headless tools -- render a screen, dump a table, probe audio
sylpheed-viewer/ the Explorer: a human's window onto the disc. STATIC data only
sylpheed-export/ disc -> the open, moddable asset tree
port/ the Godot 4 project. Reads open formats ONLY
authored/ decisions that are NOT on the disc, each with its reason
data/
base/ generated by the exporter. Gitignored, never hand-edited
mods/ drop-in overrides. Yours
docs/
re/ the corpus: findings, refutations, method traps
game/ how the game is navigated -- menus, modals, flight
port/ the port's mission, its handoff contract, modding rules
agents/ how the agent team works together
tools/ capture harnesses, probes, the share tool
exchange/ transient inter-agent files. NOT in git
docker/ the agent containers
Where to start
docs/re/INDEX.md— what is decodeddocs/re/REFUTED.md— what has been tested and dieddocs/re/METHOD.md— traps this project has already paid fordocs/game/navigation.md— how the game is navigateddocs/port/MODDING.md— why the asset tree looks the way it does
Xenia Canary is a separate repository: it is a fork tracking upstream, and it carries our instrumentation.
Conventions
Confidence is per claim, never per document: ✅ CONFIRMED · 🟡 PROBABLE ·
❔ HYPOTHESIS · ❌ REFUTED. A withdrawn result is kept with its reasoning
rather than deleted — that is why the numbers here can be trusted.
